Ordering the right part for an 1840 Uni-Loader skid steer loader comes down to what these 618 pages put in front of you: the full Case 1840 parts catalog PDF, printed by J I Case. Exploded views run from the 4-390 engine and its emissions certified variant through fuel injection, the front and rear harnesses, tandem pump linkage, loader lift and bucket hydraulics, control valves, couplers and ROPS. Hydraulics take the biggest share of the book, and callout numbers tie each hose, drive motor and coupler to a part number, with serial break notes marking which version fits your machine. Measure before you order: the fan belt runs 1574.8 mm, and the negative battery cable comes in at 38 inch on the 12 volt system. Some jobs are just you and the loader, nobody to ask. Search a part number, use the bookmarks to land on the right group, then print the page and let it get greasy on the bench.
Complete the set for your 1840
